NOTE: Based on data from 50 states, the District of Columbia, and the Commonwealth of Puerto Rico. The data in this table are rates of victimization based on the number of investigations and assessments by Child Protective Services that found the child to be a victim of one or more types of maltreatment. This is a duplicated count because an individual child may have been determined to have been maltreated on more than one occasion. Substantiated maltreatment includes the dispositions of substantiated, indicated, or alternative response victim. States vary in their definition of abuse and neglect. Rows total to more than 100 percent because a single child may be the victim of multiple kinds of maltreatment. The category of unknown includes missing data and children older than 17 years.
